A hybrid electric vehicle comprises an engine and an electric propulsion motor, and the vehicle is operable in an HEV mode in which the engine may be switched on automatically during a drive-cycle by a controller and an electric vehicle (EV)-only mode. The vehicle is operable in a plurality of attribute modes in which operating parameters of the vehicle are changed by the controller responsive to the identity of the selected attribute mode, wherein, when in the HEV mode and a first attribute mode is selected, selection of the EV-only mode by the driver results in assumption of the EV-only mode and continued operation in the first attribute mode, and, when in the HEV mode and a second attribute mode is selected, selection of the EV-only mode results in assumption of the EV-only mode and automatic de-selection of the second attribute mode. |
